Maintenance

4.Start the vacuum pump and open the shut-off valve to the high vacuum gauge manifold only. After the compound gauge (low side) has dropped to approximately 29 inches of vacuum, open the valve to the vacuum thermocouple gauge. See that the vacuum pump will bank-off to a minimum of 50 microns. A high vacuum pump can only produce a good vacuum if its oil is not contaminated.

5.If the vacuum pump is working properly, close the valve to the vacuum thermocouple gauge and open the high and low side valves or the high vacuum manifold set. With the valve on the charging cylinder closed, open the manifold valve to the cylinder.

6.Evacuate the system to at least 29 inches gauge before opening valve to thermocouple vacuum gauge.

7.Continue to evacuate to a minimum of 250 microns. Close valve pump and watch rate of rise. If vacuum does not rise above 1500 microns in three minutes, system can be considered properly evacuated.

8.If thermocouple vacuum gauge continues to rise and levels off at about 5000 microns, moisture and non-condensables are still present. A leak is present if the gauge continues to rise. Repair and re-evacuate.

9.Close valve to the thermocouple vacuum gauge and vacuum pump. Shut off pump and prepare to charge.

Charging the System

Charge the system with the exact amount of refrigerant. Refer to the unit nameplate for the correct refrigerant charge. An inaccurately charged system will cause future problems.

Charging Procedure

1.When using an ambient- compensated calibrated charging cylinder, allow liquid refrigerant only to enter the high side.

2.After the system receives all the refrigerant it requires, close close the valve on the high side of the manifold.

3.Start the system and charge the balance of the refrigerant though the low side. Do not charge in a liquid form.

4.Close the low side valve on the manifold and pinch-off both process tubes. Remove the manifold set. Crimp shut the open ends of the process tubes and braze.

5.Recheck for refrigerant leaks.

Refrigerant

Do not use a refrigerant other than that shown on the unit nameplate. Follow all precautionary measures recommended by the refrigerant manufacturers.

Line Piercing Valves

Line piercing valves may be used for diagnosis but are not suitable for evacuating or charging due to the minute holes pierced in the tubing.

Line piercing valves must not be left on the refrigerant system. The connection between the valve and the refrigerant tubing is not hermetically sealed and will eventually leak.

Open Lines

Never leave refrigerant lines open to the atmosphere when processing the refrigeration system. Water vapor may enter the lines and cause improper evacuation.

Operating Test

The final step in a successful repair is an accurate operating test. Follow the cooling and heating performance tests on pages 36 - 37 to make sure the product is performing to design standards.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
